BARBED FENCE WiRE.

SPECIFICATION forming part of Letters Patent Ne. 313,929, dated March17, 1885.

Application filed February 5, 1883. (Modch) .To all whom it mayconcern.-

Be it known that I, WILLIAM EDnNnoRN, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inBarbed Fence-Wire, of which the following is a specification.

My invention relates to an improvement in barbed and twined or twistedfence-wire in which two longitudinal wires are employed.

My improvement consists in wires twined or twisted one over the other,having a very thin, flat web of metal connecting their adjacent sides ofabout one-third or one-fourth the thickness of the barb, the latterbeing about two-thirds the thickness of oneof the wires, this thinwebbeiug left in the process of manu facture to prevent longitudinaldisplacement of the twin wires in the process of twining or twisting,while the thin web does not interfere with the twining or twisting ofone wire over the other within a very short distance, as usual.Perforations or holes in the web are provided for the barbs.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which Figure1 is a plan View of twin main wires connected together on adjacent sidesby a very thin, flat web merely of sufficient thickness to keep themfrom moving longitudinally in the process of twining or twisting onewire over the other. Figs. 2, 3, 4., 5, 6, 7, 8, 9, 10, 11, 12,13, 14,15, 16, and 17 show various forms of barbs applied to such twin wire;Figs. 2 and 3, 4 and 5, 6 and 7, 8 and 9,10 and 11, 12 and 13, and 14and 15 being respectively transverse sections and plan views, and 16 and17 transverse sections, of portions ofmy improved twin wire, thetransverse sections of the twin wire showing the barbs in elevation. Iprefer the form of barb shown in Figs. 4: and 5.

No description of the various forms of barbs illustrated is given, asthey are clearly shown in the drawings.

A A represent the main wires connected by a thin, flat web, 0, which hasperforations or holes 13 at suitable distances apart to receive barbs D,which may be of any desired shape or form, several being shown. The

wires may be drawn to the proper size to leave the very thin, flat web0, which may be done by drawing a No. 5 wire rod with one draft to No.71 then passing it through two successive pairs of rolls, the first pairof rolls to flatten it to, say, No. 12}- 6, and thesecond pair of rollsto divide it centrally, the second pair of rolls being adjusted toreduce the wire into two parts, leaving a thin Web, 0, between them.After thus reducing the rod, which leaves a web, as shown, aboutonethird or one-fourth the thickness of a barb, which is abouttwo-thirds the thickness of a main wire, the web perforated, and thebarbs applied, the main wires are twined or twisted together, as shownin Fig. 17. Barbed and twined or twisted fence-wire thus produced hasall the advantages of two-strand cable, where the strands are notconnected by a web, is cheaper, because wires of less diameter can beused and of the same strength, and an article of better quality andappearance pro- .duced, for where two unattached wires are used theygenerally vary in size and temper, one being softer than the other, andin cit-her of these cases the wire which is softer or of less diameterwinds around the other, which results in an ill-appearing product, andalso in oneinferior in quality, because the larger or harder wire beingstraight and the other wire winding around it, as stated, they cannotexpand and contract together in different temperatures, while with myconstruction a difi'erent article is produced, for if one wire happensto be thin or soft in places the other is correspondingly thin or soft,and thus they must twine or twist uniformly throughout.

I am aware that Wire grooved longitudinally, leaving a web of sufficientthickness to be nicked up to form barbs, is old, that such web has beenslotted to receive barbs, and that such wire has been slightly twisted.Such construction,therefore, I do not claim,broadly, as in no instancethat I am aware of have two complete main wires been formed with averythin, flat connecting-web while permitting the wires to be twined,twisted, or rolled sidewise one over the other, as usual.

I should state that the drawings represent my wire on a very largescale, to clearlyindicate the details of construction.
